MONTREAL — HPQ Silicon Inc. announces the successful completion of Test Series #7 of the proprietary Fumed Silica Reactor (FSR) pilot plant developed by its wholly owned subsidiary, HPQ Silica Polvere Inc. (HSPI).

The pilot plant, designed and built by engineering partner PyroGenesis Inc., reportedly marks another step in HPQ’s attempts to commercialize a direct-quartz-to-fumed-silica manufacturing process that eliminates the need for intermediate steps and tries to reduce the total energy and carbon footprint of production. The process reportedly uses a plasma-based reactor to convert quartz directly into fumed silica.

“Each test series brings us closer to proving that low-energy-low-carbon, direct-from-quartz fumed silica can be produced reliably and competitively,” said Bernard Tourillon, President and CEO of HPQ Silicon Inc. and HPQ Silica Polvere Inc. “This work continues to validate years of R&D investment and demonstrates the industrial scalability of HPQ’s proprietary process.”

A set of samples have reportedly been shipped to an accredited third-party laboratory for certification, with results expected within ten business days.

“Once these results are received, we will be able to define the goals and engineering upgrades for Test Cycle #8, which we anticipate will take us closer to the end goal of the highest fumed silica surface area grades of 300 m²/g,” added Tourillon. “We’re moving from proof-of-concept toward measurable market traction—aligning with HPQ’s broader objective of creating low-energy carbon, high-value materials that compete globally while supporting North American supply-chain resilience.”
